That is a very deceptive video/article (at least the first half above the paywall). It is true that a few of these sats will have to come down each day, but the video is of a booster failure/explosion, not a normal planned obsolescence sat re-entry.
And re-entry is part of the cleanup plan. All satellites responsibly launched need a plan to deal with possible orbital waste. By decommissioning in this way, we're reducing overall impact of the constellation.
Given the immense possible good worldwide internet can provide, and the virtuous cycle it creates for the US launch industry, it's really hard to take these claims seriously.
It is impossible to make any improvement without some impact. We're way, way past any real problems when discussing a few 100kg of metal falling into the upper atmosphere every day.
Growth versus preservation. India is trashing its air quality burning coal near its cities. Yet that power is lifting millions out of poverty and into the world's second-largest middle class.
Everyone would prefer clean air ceteris paribus. But for a lot of those people, economic security is "more important than preserving the environment."
I believe that an atmosphere compatible with human life is a bit more useful than internet by satelite. The fact that the impact of re-entry of satelites is absolute insane. Any good engineering company would study the whole impact of scaling up before doing so. The fact that spacex didn't do that is really worrying and regulation should come to stop what they are doing asap until the impact is better understood. Some more serious engineers at Japan aerospace are studying wooden satelite which is a quite approach to the problem.
I am not aware of threats to the atmosphere from the entry at a 100kg/day scale. And nobody is. At this point risks are hypothetical to the ozone or other layers.
if the aersols do cause any problems we're done for quite a while as they do not seem to come down. As I understand it the amount of aerosol will be quite significant in this layer of athmosphere. https://csl.noaa.gov/news/2025/427_0428.html
if you combine all the fallen starlink satellites and the debris/waste they produce in a year, it comes down to about less than 0.1% of what the earth receives from space in the same year
Okay, that makes sense. The reading I did indicated that the composition of the man-made mass is very different, and could greatly elevate the amount of certain elements released in the upper atmosphere, like aluminum. Is this not cause for concern?
